Abstract
An inverter device uses an inverter to convert DC voltage supplied from a rectifying component to AC voltage and applies the AC voltage to an inductive load. The inverter device includes a shunt resistor provided on a direct-current link interconnecting the rectifying component and the inverter, a first terminal passing current to the shunt resistor, a second terminal to which the current from the shunt resistor flows, and a printed board having a conductive pattern with first and second conductive pattern components joining the shunt resistor and the first and second terminals, respectively. The first conductive pattern component includes a first central region connecting right and left side ends of the shunt resistor to right and left side ends of the first terminal, and first right and left side protruding regions. A ratio of areas of the first left and right side protruding regions is 0.6 to 1.6.
